Model of Nucleon Clustering and Fragment Formation in Fission of Heavy Nuclei

The problem of theoretical description of the formation of fission fragments was considered within the framework of an extended Vicsek-type collective model. The non-mean-field approach is based on microscopic modeling of the nucleon clustering as a phenomenon of particle aggregation due to short-range mutual interaction. Numerical computer simulations were carried out for the 208Pb cluster, which is observed experimentally in the multimodal fission of heavy and superheavy nuclei.
